## Summary description

Dobsonian Skywatcher 12" Flex Tube (305/1500) is a Newtonian reflector on a Dobsonian mount with 305 mm aperture and 1500 mm focal length. Designed for deep-sky and planetary observation, it offers high light-gathering power and a compact collapsible tube for easier storage and transport. Suitable for amateur astronomers seeking large aperture performance and simple alt-azimuth operation.

## Long description

The Dobsonian telescope Skywatcher 12" Flex Tube 305/1500 is a Newtonian reflector on a simple alt-azimuth Dobsonian mount, featuring a 305 mm primary mirror and a 1500 mm focal length. The large aperture provides strong light-gathering ability for observing faint deep-sky objects, while the collapsible (flex) tube reduces storage volume and makes transport easier. The instrument is designed to deliver high-contrast views of planetary detail, star clusters, nebulae and galaxies with straightforward setup and manual pointing.
Advantages
The 305 mm aperture increases image brightness and resolution compared with smaller amateur telescopes, improving visibility of faint nebulae and distant galaxies. The Dobsonian mount offers intuitive alt-azimuth movement for fast manual tracking and simple operation without complex electronics. The flex tube design allows the optical tube to collapse to a shorter length for convenient transport and storage while maintaining the full focal length when extended. The robust rocker box mount and large bearings provide stable support for visual observing sessions.
Suitable for
Visual observation of planets, the Moon and bright deep-sky objects
Amateur astronomers who prioritise large aperture and ease of use
Portable observing sessions and star parties where easier transport is needed
Deep-sky observing of nebulae, star clusters and galaxies
Key specifications
Aperture: 305 mm (primary mirror diameter)
Focal length: 1500 mm
Optical design: Newtonian reflector
Mount type: Dobsonian alt-azimuth rocker box
Tube type: Collapsible (flex) tube for reduced storage length
Primary mirror: Parabolic mirror for improved image quality
Focal ratio: f/4.9 (approximate)
How to use
Set the telescope on a level surface and assemble the rocker box and optical tube according to the supplied mounting points, extending the flex tube to its operating length. Balance the focuser and attach an eyepiece suitable for the target; start with a low-power eyepiece to locate objects and then switch to higher magnification for detail. Use the alt-azimuth movements of the Dobsonian base to point and manually track targets across the sky. Allow the telescope to reach ambient temperature for best thermal equilibrium before detailed observing.
Usage recommendations
For best results use low- to medium-power eyepieces for wide-field deep-sky views and medium- to high-power eyepieces for planetary detail. Transport the optical tube in its collapsed state and extend it only when ready to observe. Collimation checks are recommended regularly for optimal image sharpness, particularly after transport. Use a dew shield or dew heater in humid conditions and choose observing sites with low light pollution to take full advantage of the 305 mm aperture.
